Article 45 3.

Member States shall subject registered third-country auditors and audit entities to their systems of oversight, their quality assurance systems and their systems of investigation and penalties. A Member State may exempt a registered third-country auditor or audit entity from being subject to its quality assurance system if another Member State's or third country's system of quality assurance that has been assessed as equivalent in accordance with Article 46 has carried out a quality review of the third-country auditor or audit entity concerned during the previous three years.
